Abstract
The utility model provides a one-way valve which comprises a valve body, a valve core, a spring and a plug. The valve core is installed in the valve body, the valve core is supported by the spring, the spring is pressed by water pressure, the spring can drive the valve core to carry out opening and closing motion, the head portion of the valve core is connected with the plug to be arranged at the inlet position, the plug and the valve core are of a split structure, and the plug is made of soft rubber and plastic materials. The one-way valve is simple in structure. The plug and the valve core are of a split structure, the plug is made of soft materials different from the valve core, and accordingly the problem that an existing one-way valve is untight in closing is solved.
Description
Technical field
The utility model relates to a kind of one-way valve.
Technical background
Existing individual event valve, its sealing effect is not good enough.At the state of not water flowing, water leakage fault often occurs, and, existing one-way valve, spool is generally metal material, under the bad state of water quality, is corroded than being easier to, and affects the working life of one-way valve and has the not tight situation of water of closing.Now be badly in need of improving existing one-way valve, to avoid the generation of the above defective.
The model utility content
For realizing the above, the technological scheme that the utility model provides is as follows: described individual event valve comprises valve body, spool, spring and shutoff, and spool is installed in the valve body, the spring supporting spool, and hydraulic pressure presses spring, and the spring band movable valve plug is opened and the action of closing; The spool head connects shutoff, is positioned over inlet.
Further, described shutoff and spool are Split type structure.
Further, the material of described shutoff is soft rubber and plastic materials.
This one-way valve that the utility model relates to, this valve mechanism is simple, and shutoff and spool are Split type structure, and be different from the material of spool, is soft material, can solve the situation that existing individual event valve is not closed completely.
Description of drawings
Fig. 1 is a kind of one-way valve structures schematic diagram of the utility model;
The 1-valve body; The 2-spool; The 3-spring; The 5-shutoff.
Embodiment
As shown in Figure 1, described individual event valve comprises valve body 1, spool 2, spring 3 and shutoff 5, and spool 2 is installed in the valve body 1, and spring 3 supports spool 2, and hydraulic pressure presses spring 3, and spring 3 is opened and the action of closing with movable valve plug 2; Spool 2 heads connect shutoff 5, are positioned over inlet.
Shutoff 5 is Split type structure with spool 2.
The material of shutoff 5 is soft rubber and plastic materials.
This individual event valve that the utility model relates to, simple in structure, good sealing effect can increase the service life.
Embodiment described in the utility model does not consist of the restriction to the application's scope; every within the spirit and principle of the utility model design, any modification that one of skill in the art can make, be equal to and replace and improvement etc. all should be included within the protection domain of the present utility model.
